“Dear Mark and Priscilla: From parents to parents, our most heartfelt congratulations on welcoming Max to the world […]
Your commitment to making the world a better place than you found it, and to empowering everyone to help make that a reality through all the tools you’ve listed here, education for all being one of them, show that success, when shared, has a multiplier effect […] Thanks for your generosity,” read portions of the letter.

“Thanks Shakira and Geri! Your work with the United Nations has been an inspiration and we’ve enjoyed discussing each of our education projects together over the years. We look forward to you guys meeting Max soon!”
Shakira has devoted the bulk of her considerable philanthropic endeavors to early child development.
